CAUTION:
(Continued)
Be sure you have sufficient knowledge,
-
experience, the proper replacement parts
and tools before you attempt any vehicle
maintenance task.
Be
sure to use the proper nuts, bolts and
other fasteners. “English” and “metric”
fasteners can be easily confused. If you use
the wrong fasteners, parts can later break
or fall off. You
could
be hurt.
Adding Equipment to the Outside
of
Your
Vehicle
Things you rnight add to the outside of your vehicle can
affect the airflow around it. This may cause wind noise
and affect windshield washer performance. Check with
your dealer before adding equipment to the outside
of
your vehicle.
Fuel
Use premium unleaded gasoline rated at
91
octane or
higher for best performance. You may use middle grade
or regular unleaded gasolines, but your vehicle may not
accelerate as well.
At a minimum, the gasoline you use should meet
specifications ASTM
D48
14
in the United States and
CGSB
3.5-M93
in
Canada. Improved gasoline
specifications have been developed by the American
Automobile Manufacturers Association (AAMA) for
better vehicle performance and engine protection.
Gasolines meeting the AAMA specification could
provide improved driveability and emission control
system protection compared to other gasolines.
Be sure the posted octane for premium is at least
91
(at
least
89
for middle grade and
87
for regular). If the
octane is less than
87,
you may get a heavy knocking
noise when you drive. If it’s bad enough, it can damage
your engine.
If you’re using fuel rated at the recommended octane or
higher and you hear heavy knocking, your engine needs
service. But don’t worry if you hear a little pinging
noise when you’re accelerating or driving up a hill.
That’s normal, and you don’t have to buy a higher
octane fuel to get rid of pinging. It’s the heavy, constant
knock that means you have a problem.
If your vehicle is certified to meet California Emission
Standards (indicated on the underhood emission control
label), it is designed to operate on fuels that meet
California specifications.
If
such fuels are not available
in states adopting California emissions standards, your
